STOP-COCK BOX FOR SERVICE-PIPES.

SPECIFICATION forming part of Letters Patent No. 363,649, dated May 24, 1887.

Application tiled November 8,1886. Serial No. $218,295. (No model.)

T0 all whom it may concern.-

Beit known that I, JOHN H. KENNEDY, of

useful Improvements in StopOock Boxes for Service-Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in stop-cock boxes for service-pipes, in which is employed an extensible cap of considerable length, `that may be adj usted lengthwise of the box to bring the cap flush with the pavement. A locking device is provided to temporarily hold the cap at the desired elevation while the box is being set, with the arrangement of parts such that after the filling is tamped around the cap the locking device can be unlocked and the cap left supported by the filling, to the end that in case the ground is upheaved by the frost only the cap is moved andthe body of the box is not disturbed. A detachable base is provided, the saine having an upwardly-projecting annular rim made to overlap the box and turn or slide easily thereon. The rim internally has spiral grooves and the box has projecting lugs for engaging the grooves, to the end that by turning the base in one direction it is drawn upward and made to clamp the ends of the coek,the latter extending out through slots inthe body of the box, such clamping device being adapted to receive cockslof different sizes.

In the accompanying drawings, Figure 1 is' a side elevationef a stop-cock box embodying my invention, portions being broken away to show the construction. Fig. 2 is an elevation in section taken at right angles to the view shown in Fig. 1.

A represents the body of the box, the same consisting, essentially, of an upright hollow open-ended metal column.

B is a removable base, and O an extensioncap. The base has an upwardly-projecting annular rim, B', .made to iit over the lower end of the box A and to'slide or turn` easily thereon. The ri n1 B', internallyand on opposite sides thereof, is provided with grooves Ab, the

downward a short distance, and then circumferentiall y, but inclining downward, as shown.

The box A, near the bottom, has outwardlyprojecting lugs or pins. a, that operate, respectively,ir`1 the grooves b, by reason of which, when the parts are in position, by turning the base in one direction the base is drawn npward on the box.4

D is a stop-cock, the body of which is 1ocated inside the box, with the ends thereof, d, to which the service-pipe is to be attached, extending out through notches a', made in the lower edge of the box. By` turning the base as aforesaid, the latter is brought up in contact wit-h the projecting ends d, bringing the latter into the notches a. and clamping them, in which position the cock is ready for attaching the service-pipe. l

As the notches a are triangular on top, the

`lines diverging abruptly, two or three sizes of the cock may be secured, respectively, in the clamp. The capO is of considerable length, and iits easily oven,1 the top of the box. A lug, a2, projects from the box and operates in a vertical groove, c, made on the inside of the cap. This groove is in open relation with a series of notches, c', made along the one side of the groove, the notches being respectively adapted to receive the lug a2. The groove at the bottom hasV a lateral extension, c2, from the end of which latter the groove c3 extends same extending from the top edge of the rim to the lower edge of the cap, the lateral portion of the groove serving as a stop to prevent the cap from being inadvertently pulled off the box in handling. The cock is operated by means of a detachable square rod, E, the latter being made of suitable length to extend well up into the cap, whereA it is easily reached with a socket-wrench, the head of the caphaving an opening for the purpose, said opening being closed by a screw-plug, F. The latter has preferably a triangularshaped head, f, made flush with the head of the cap, so that it is out of the way and cannot be turned by an ordinary wrench. The parts being assembled, the box is set in the ground and the service-pipe connected. The cap is raised or lowered to bring the top thereof to the desired elevation ilush with the pavement, and is se- IOO cured temporarily by turning the cap to bring the lug a2 into one ofthe notches c. The till` ing, after it is packed, will support the cap, and the latter s then turned to disengage the lug a2 from the notch c', bringing the lug into the vertical not'ch c, in which position of parts,

-it' the ground freezes to the'cap and is upheaved by the frost, the cap may move vertically with the ground without disturbing the box A, and in such cases the pavement and cap will usually retain their relative positions. The box, base, and cap are usually of castiron. Y .c

1. As a new article of manufacture, a stopcock box for service-pipes, consisting, essentially, of a body, cap, and base, the body and cap being provided with devices for temporarily locking them together while the box is being placed in position, and the base adapted to overlap and tit loosely on the box and pron vided With inclined grooves adapted to engage projecting lugs on t-he box, substantially as and for the purpose set forth.

2. In a stop-cock box for service-pipes, the combination, with the body of the box, of a detachable base, the latter being made to over lap and t loosely on the box, the base having inclined grooves and the box having projecting lugs for engaging the grooves, the 'parts' being arranged substantially as indicated, for

clamping the cock between the base and box,

substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 5th 3 5 day of October, 1886.
